Abstract

Purpose

To evaluate the outcomes of flanged intraocular lens fixation combined with microhook trabeculotomy.

Patients and methods

This study was a retrospective case series and included nine eyes of nine exfoliation glaucoma patients with subluxated lens or intraocular lens who underwent flanged intraocular lens fixation combined with microhook trabeculotomy between May 2019 and February 2020 at the Kochi University Hospital. The mean best-corrected visual acuity, intraocular pressure, and number of antiglaucoma medications were compared before and after surgery.

Results

The mean follow-up period was 5.67 ± 2.50 months. The mean best-corrected visual acuity improved significantly from 0.83 ± 0.72 preoperatively to 0.22 ± 0.34 at the last visit (p = 0.015). The mean intraocular pressure had significantly reduced from 27.1 ± 8.12 mmHg preoperatively to 13.2 ± 3.73 at the last visit (p = 0.008). The mean number of antiglaucoma medications decreased significantly from 4.56 ± 1.88 to 2.0 ± 1.0 at the last visit (p = 0.008). Postoperative intraocular pressure control to 21 mmHg or lower was achieved or maintained in all patients. Postoperative vitreous hemorrhage was observed in six eyes (66.7%), two of which needed reoperation.

Conclusions

This study showed that flanged intraocular lens fixation combined with microhook trabeculotomy might be effective for exfoliation glaucoma with subluxated lens or intraocular lens.
